Riikira's first appearance was in the thank-you credits for Kitcaliber's ИΣVΣRLAИD SØUИDGIRL$, released 17 April 2014. She was listed next to her radio frequency, M027. Ren had asked Lewis to come up with a "future death-warrior" name to appear in the album's thanks. Shortly afterwards, Riikira was developed into a character and new alias to produce music similar to that of Kitcaliber's.
